Got my in app purchase but wasn’t charged
A couple days ago I purchased some things through in app purchasing. Usually when I buy something it is instant and I can see it was taken from my cashapp. But now it isn't showing that it charged my card and I don't have any balance in apple, no gift cards either. Why is it doing this all of a sudden? Am I going to be charged in the future? I don't even have anymore money left on my cashapp so what's going to happen? When I went to buy my things it said I was using apple pay. Any help?
